SASH-WEIGHT-CASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 451,707, dated May 5,1891.

Application filed Tune 10, 1890- Serial No. 354,901. (No model.)

To all whom, it may concern.-

Be it known that I, FREDERICK N. CLINE, a citizen of the United States,residing at Chicago, Illinois, have invented certain new and usefulImprovements in Sas11-IVeight-Casting Machines, of which the followingis a specification.

My invention relates to sash-weight-casting machines wherein a series oflongitudinally-divided molds hinged together are secured upon a rotatingframe, the rotation of which permits the molds to be filledsuccessively, and after they are filled carries them into contact withtripping devices, whereby the members are separated to discharge thesash-weight, which drops upon a traveling belt or apron and is conductedaway from the machine. In a machine of this character it is sometimesdesired to make weights of various sizes at the same time, and as thelength of the weight is usually increased with but slight change in thediameter the molds must be correspondingly lengthened. IIeretofore thishas not been attempted, because it has been considered necessary tomaintain the rotating frame at a fixed distance above its base orsupport,in order that the molds might be brought to engage the trippingdevice. I have provided for using molds of varying lengths on the samerotating frame by making said frame vertically adjustable with referenceto the base, and I have also adapted the tripping devices to operatewithout adjustment in the several positions of the frame. I have alsoprovided an improved means for clamping the members of the molds duringthe act of forming the metal and until they are ready to engage thetrip. I have improved other features of construction, which will behereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of anapparatus embodying my improvements and comprising a rotating framebearing thirty (30) molds, with tripping projections located at oppositepoints in the path of rotation, whereby molds on opposite sides of theframe are filling while others are discharging. Fig. 2 is a plan View,

and Fig. 3 is a side elevation. Fig. 4 is a central vertical section ofthe central bearing of the rotating frame and of thebearings for avertical power-shaft, the latter being shown in broken elevation. Fig. 5is a transverse section on the line 5 5 of Fig. 4. Fig. 6 is a detailview of an adjusting device for the mold-clamps. Figs. 7, S, 9, and 10are detail views of the mold.

In the drawings, A represents the base of the machine, which has a. step13 to provide a bearing for a vertical driving-shaft C.

D is an annular bushing fitted to the bearlugs for the end of the shaft,and E a bearits lower face, rests upon these balls, and

its upper end is bored to a larger diameter than the shaft and threadedinteriorly, as shown at g. Lever-sockets G are provided in lugs formedon the sleeve G to adapt it to be rotated. A sleeve H, having exteriorthreads 71. and a cap h, is keyed on shaft 0. The sleeve Gr has alongitudinal recess cut on its outer face and a threaded segment I isplaced therein, the recess being of such depth as to permit of thesegment being drawn away from looking engagement with the threads of thesleeve H. Set-screws J are tapped through the wall of sleeve G and intosegment I, and upon being turned operate to force the segment intolocked engagement with sleeve H, so as to cause the rotation of sleeve Gwith H, or to withdraw the segment to permit the turning of sleeve Gindependently in order to adjust the sleeve I-I vert-ically.

L represents the mold-wheel, whose hub L is keyed to shaft C and restsupon the head of sleeve H, whereby it is elevated or lowered when saidsleeve is adjusted as, before described. Power is applied to shaft C inany convenientmanner-as,forexample,by means of the gearing shown in Fig.3.

The molds are shown in detail in Figs. 7 to 10, inclusive, of thedrawings, and they consist of two members MM, the former being bolted orotherwise secured to the rim of the mold-wheel and the member M .beinghinged to member M and bearing the anti-friction rollers m and thet1'ipping-lever"m, which is secured with the projecting lower end of thepart M. These molds may be of different lengths, and to adapt theirtripping-levers to be operated upon, in order to open the molds anddischarge the sash-weights, I provide the tripping devices shownparticularly in Fig. 1 of the drawings and consisting of the bracket N,having the vertically-positioned roller or sleeve 02, of such length asto engage the. variously-positioned tripping-levers of the' molds. Ifthe metal is poured at more than one point at the same time, it will benecessary to employ more than one of these tripping devices.

Referring particularly to Figs 1, 2, 3, and 6 of the drawings, theconstruction of the spring clamping devices for holding the swingingmember of the mold during the operation of filling will be bestunderstood. 0 represents a standard, which is adj ustabl y se- 1 curedto the base of the machine by means of the set-screws O',working inapertures o'of the base, and the set-screw P furnishes means for movingthis standard toward and from the? mold-wheel. The upright portion ofthis standard is vertically recessed, and within the recess slides asecond standard Q, having I the rack g on its lower end. A pinion R is journaled in the standard Q, its teeth enmeshing with the rack-teeth ofstandard Q, and a pivoted dog or pawl S engages the teeth of this pinionto lock the standard Q in the desired position. The upper end of thestandard Q bears the rods T,-each of which carries a bow-spring U, whoseends are secured in keepers v on curved plates V, against which thefriction-rollers of the molds bear during the operation of filling. Therods T are threaded and nuts t are applied to the threads of the rodsfor. the purpose of adjusting the tension of the bow-springs. Iprefer toemploy two of the standards 0 and two of the plates V, so as to securelyclamp the hinged members of the mold during the pouring of the metal,and the employment of two of these clamping-plates, together with thedescribed means of adjustment, provides for any contingency likely toarise, owing to the substitution of longer or shorter molds in themoldwheel or of molds of different diameter.

The operation of the apparatus willbe readily understood from theforegoing description, I

and its capacity for producing a variety of sizes of sash-weights at thesame time-will be found of great convenience and utility.

I claim- 1. In an apparatus for making sash-weights, the combination,with a vertically-positioned rotatable driving-shaft having amold-bearing frame secured thereto, of two oppositeiy-threaded sleeves,one secured to the shaft and the other having a bearing upon a fixedpart of the apparatus, and means for locking said sleeves againstmovement upon each other, substantially as described.

2. In an apparatus for making sash-weights, the combination, with avertically-positioned rotatable driving-shaft having a mold-bearingframe secured thereto, of two oppositelythreaded sleeves, one secured tothe shaft and the other having a bearing upon a fixed part of theapparatus, and a threaded segment seated in a. recess in the outersleeve and engaging the-threads of the inner, and set-screws tappedthrough the wall of the outer sleeve and in to said segment, whereby thelatter may be adjusted to lock and unlock the sleeves, substantially asdescribed.

3. In an apparatus forinaking sash-weights, the combination, with ahorizontally-rotating mold-frame bearing molds whose members are hingedtogether, of curved plates secured in proximity to the path of the moldsand adapted to engage the swinging member thereof to clamp it upon itsfellow, .and bowsprings having their ends loosely secured with theplates, and means for adjusting the tension of said springsindependently, whereby the plates may be separately adjusted,substantially as described.

t. Inan apparatus for makingsash-weights, the combination, withahorizontally-rotating mold-frame bearing molds whose members 7 arehinged together, of spring-pressed clamping-plates located in proximityto the path of the mold and adapted to clamp theswinging member thereofupon .its fellow, a sliding standard to support-said plates, saidstandard having a rack and pinion whose teethare enmeshed with therack-teeth, and a pivoted pawl or dog to lock the pinion and thereby thesliding standard, substantially as described.
